DUMPING-WAGON.

Specification of Letters Patent.

specification.

My invention relatesto dumping wagons and particularly to dumping wagonsused especially for road-making and similar purposes and so designedthat the gravel, sand, crushed stone and thelike carried by the wagon isspread by the same itself so as to avoid as far as possible subsequent,raking or shoveling in order to properly lay the discharged load.

My obj ect'is to so constru a wagon of the kind indicated that theoperation of spreading the load. will be rendered extremely simple andconvenient; this object I havelaccoinplished by constructing the wagonsubstantially as herein described and shown whereby it will be foundthat the expense of building the same is kept well within a reasonableamount and substantially all' of those features which have provednecessary to wagons of this type are retained.

-" My invention will be found fully illustrated 1n the accompanyingdrawings, wherein,

kind indicated provided with my improved mechanism for spreading theload; Fig. 2 is a sectional view taken just above a certain shaft i;and, Fig. 3 is an enlarged view in side elevation of the essentialparts. of said mechanism. I

(L designates the wagon body and Z) the the front wheels support a yokecwhich in turn sustains the front part of the wagon body a, the bottom (1of the latter having quite a pitch or incline, as shown, by virtue ofsaid yoke and also by virtue of the rear axle e being U-shaped as shownin 1 so that the rear of the wagon approaches rather close to' theground. This construction leads to the load discharging itself freely,by gravity, as'soon as released, and to its not unduly scattering.

f is the tail-gate which is pivoted in brackview ofa wagon of the thepawl 0 normally against the ratchet.

' throwing the lever ets g at the top of the back of the wagon, the backof the wagon being so formed thatwhen the tail-gate is closed its lowerend is forward of the perpendicular extending through its upper orpivoted end; thus, however little of the load may remain inthe wagonbodyupon discharging, if the tail-gate is free or released there isalwaysan outlet left for its escape. In brackets h bolted to the yoke cis-journaled a shaft i on the ends of which are drums 7', and aroundthese drums are wound chains or the like 7c extended rearwardly andconnected to the tailgate f at the sides thereof. Next to the left handdrum is aratche't wheel [which is fixed on, the shaft. Next to theratchet wheel is a hand lever ,m which is fulcruined on the shaft i andextends up wardly alongside of the front of the wagon, in convenientreach of the drivers seat n.

Thls lever m carries a pawl owhich is piv'oted thereto and engages theratchet Z, being adapted for control from a hand grip p in-the form of a-crank pivoted to thelever m and connected withthe pawl 0 by apitman 9.Another pawl 1' is pivoted on the drivers foot board 3 and cooperatesWith-the pawl 0 to hold the ratchet Z against'back action.

N ext to the lever m is a friction wheel 15, fixed on shaft i, andaround this friction wheel and adapted toperi herally engage the sameextends a band bra e u, secured on a pin 42 projecting from-the yoke cat one end and having its other end projecting over the foot board'inconvenient reach of the drivers foot, asatw.

The weight of the parts p, g and 0 will kepp 11 order to limit' themovement of pawl 1" when out of engagement with the ratchet I provide itwith alug 90 adapted to engage a pin y on'the foot board.

In view of the foregoing description it will be seen that the driverfrom l'llS "seat can close the tail gate, pawl 1 being against the.

ratchet, by vibrating the lever m, the pawl 0 slipping freely over theratchet on the back stroke and turningthe ratchet on the forward stroke,the ratchet being each time held against backward rotation by the otherpawl. When the load is to be discharged, the pawl r may be eitherunshipped by the driver's foot or by releasing the pawl o and mforwarduntil pawl 0' discharges awl r'froni the ratchet, leaving the shaft i ccto rotate as the weight of the load pushes the tail-gate open, unwindingband brake.-

the chains from the drums 7'. In order to ad- 1 just the distance towhich the tail board is thus permitted to open, the driver may apply theband brake'w with his foot. But slnce, by accident, the driver may notbe prepared to apply the band brake upon the release of the s aft i andin order to place the whole 0 eration of dumping within the control of te drivers hand, alone, I provide the band brake with a projection 2,which may be in theform of a. bend therein, see Fig. 3, with which isengaged a stud Z on the lever m. The arrangement of the parts 2 and [ispreferably such that as the lever mis thrown forward for the purpose ofunshipping pawl r, the studwill engage the projection z and bring theband brake into action, to some eX- tent at least, justbefore the pawl ris released; in order to continue the action of the band brake, thedriver may either continue to use the lever m or apply his foot to theHaving thus fully described invention, what I claim as new and desire tosecure by Letters Patent is:

, 1. The combination of the wagon bodyhaving a gate permitting thedischarge of its load, a rotary shaft, operative connecting meansbetween the shaft and the gate, a manually o erated controlling device,a ratchet on tfie shaft, a pawl on saiddevice, means for manuallycontrolling the pawl, and another pawl pivoted independently of saiddevice and relatively in advance, and projecting into the path offorward move- 'ment, of the other pawl whereby to be thereby engaged andcaused to disengage the ratchet,

substantially as described.

2. The combination of the wagon body having a gate permitting thedischarge of its load, a rotary shaft, operative connecting meansbetween the shaft and the gate, a

manually operated controlling device, a,

rotary shaft, apart to be actuated fromv said I shaft, a flexibleconnection connecting said part and the shaft,-a controlling device.,-aratchet on the shaft, a pawl on said. device adapted to engagethe'ratchet to effect the relative advance of the shaft, means for controlling the independent y of said device and adapted to engage saidratchet to prevent reverse-mo'vement of the shaft, said other pawlprojecting into the path of forward movement of the pawl, and anotherpawl pivoted' first-named pawl whereby to be thereby engag-ed and causedto disengage the ratchet, substantially as described.

In testimony, that I claim the foregoing, I' l have hereunto set my handthis 7th day of December, 1906;
